AjaxResponse

public AjaxResponse(com.webobjects.appserver.WORequest request,
                    com.webobjects.appserver.WOContext context)

Method Detail

addAjaxResponseAppender

public static void addAjaxResponseAppender(AjaxResponseAppender responseAppender)

Add a response appender to the list of response appender. At the end of every AjaxResponse, the AjaxResponseAppenders are given an opportunity to tag along. For instance, if you have an area at the top of your pages that show errors or notifications, you may want all of your ajax responses to have a chance to trigger an update of this area, so you could register an AjaxResponseAppender that renders a javascript block that calls MyNotificationsUpdate() only if there are notifications to be shown. Without response appenders, you would have to include a check in all of your components to do this.

Parameters:

responseAppender - the appender to add

generateResponse

public com.webobjects.appserver.WOResponse generateResponse()

Specified by:

generateResponse in interface com.webobjects.appserver.WOActionResults

Overrides:
